SBIR Phase I: Treatment of Perchlorate Contaminated Water Using Surface Engineered Super Paramagnetic Iron Oxide Nanoparticles

这个SBIR第一阶段项目将开发一种先进的最先进的高氯酸盐修复技术，使用带有选择性高氯酸盐离子受体的磁性纳米颗粒。离子交换技术是目前应用最广泛的处理高氯酸盐含量低于100 ppb的水的技术，但其缺点是需要对高氯酸盐树脂进行最频繁的再生或处理。本项目将研究使用功能化的磁性纳米颗粒与某些特定的阴离子受体选择性结合CIO4的可行性。拟议项目的更广泛/商业影响将是消除饮用水水源中的高氯酸盐污染。美国环保署估计，在美国生产的高氯酸盐中，约90%由军方或NASA使用。仅在加利福尼亚州，就已在350多个饮用水水源中检测到高氯酸盐污染。据估计，美国的高氯酸盐清理费用超过3亿美元。一种具有成本效益和环境可接受的技术可以集中在估计价值6000万美元的高氯酸盐去除市场中的一些市场份额。

This SBIR Phase I project will develop an advanced state-of-the-art perchlorate remediation technology by using magnetic nanoparticles functionalized with selective perchlorate ion-receptors. Ion exchange, which is the most widely used technology for treating water containing less than 100ppb of perchlorate, has the drawback of needing frequest regeneration or disposal of the perchlorate-laden resins. This project will investigate the feasibility of using functionalized magnetic nanoparticles with certain specific anion receptors to selectively bind CIO4. The broader/commercial impacts of the proposed project will be the removal of perchlorate contamination from drinking water sources. EPA estimates that about 90% of the perchlorate manufactured in the U.S. is used by the military or NASA. Perchlorate contamination has been detected in over 350 drinking water sources in California alone. Perchlorate cleanup in the U.S. is estimated to cost over $300 million. A cost-effective and environmentally acceptable technology could focus on some market share of the estimated $60 million market for perchlorate removal.
